As seen in http://code.google.com/apis/desktop/docs/gadget_apiref.html#elements
there is an attribute "count" and a method "item()". You can use
element.children.count to get the number of children. You can also use
element.children.item(idx) or element.children.item("name") to get a
child directly.
Some major difference between this item() and the getElementsById()
function are:
- item() only returns one element, not all elements that match
- getElementsById() works recursively while item() only finds direct
children.
- item() can be called with the index of the element or the name of
it. There is no id="xx" attribute in Google Desktop, only name="xx".
In your case you would call the following code to change the value of
your "'b'+x + '_' + y" element which is assumed to be a direct
descendant of the element named "foo".
var ele = foo.children.item('b' + x + '_' + y);
ele.value = "bar";
Hope this helps,
Benjamin
